However, in the conventional connector with a locking mechanism, the structure of the locking mechanism is complicated and needs to be formed by bending and molding several times. Therefore, it is not easy to manufacture the conventional connector with a locking mechanism, and thus the production cost is high.
Consequently, because of the above technical defects, the inventor keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
The object of the present invention is to provide a connector with a locking mechanism, in which an elastic arm extends from a pivot hole in a locking piece, so that the structure of the locking piece is simpler and can be manufactured more easily. In this way, the production cost can be reduced.
For achieving the object described above, the present invention provides a connector with a locking connector, which includes: an insulating body provided with an accommodating trough on two opposing sides respectively, the insulating body being provided with a pivot shaft in the two accommodating troughs respectively; a plurality of terminals provided in the insulating body; a pair of locking pieces provided in the two accommodating troughs respectively; each locking piece comprising a base portion, a hook formed by extending from one end of the base portion, and a pressing portion formed by extending from another end of the base portion, the base portion being provided with a pivot hole, the pivot hole being fitted with the pivot shaft of the insulating body, the pressing portion extending outside of the insulating body, and the locking piece being formed with an elastic arm by extending from a wall surface of the pivot hole, the elastic arm abutting against the pivot shaft; and a metallic casing provided on the insulating body.
The present invention has advantageous effects as follows. In the locking piece of the present invention, the elastic arm is formed by extending directly from the pivot hole to correspond to the pivot shaft of the insulating body, so that the structure of the locking piece is simpler and can be manufactured more easily. In this way, the whole production cost can be reduced.
In order to further understand the characteristics and technical contents of the present invention, a detailed description is made with reference to the accompanying drawings. However, it should be understood that the drawings are illustrative only but not used to limit the present invention thereto.

The insulating body 10 is made of insulating plastic materials. The insulating body 10 comprises a base portion 11, two side portions 12 and two guiding portions 13. The base portion 11 is provided with a plurality of terminal troughs 14. The terminal troughs 14 penetrate through the rear end surface of the base portion 11.
The two side portions 12 are formed on two opposing sides of the base portion 11 respectively. The two side portions 12 are provided with two accommodating troughs 15 to correspond to the pair of locking pieces 30. The two accommodating troughs 15 penetrate through two side surfaces of the insulating body 10. The insulating body 10 is provided with a pillar-like pivot shaft 16 in the two accommodating troughs 15 respectively. One side of the pivot shaft 16 is recessed radially to form a recess 161. The pivot shaft 16 is formed at the recess 161 with a curved surface 162 and an abutting surface 163 connected with the curved surface 162.
Each of two side portions 12 is provided with a first fixing hole 121 and a second fixing hole 122. The first, second fixing holes 121, 122 penetrate through the top surface and the bottom surface of the two side portions 12. The rear end and one side of the two side portions 12 are provided with a locking body 17 respectively.
The two guiding portions 13 are formed by protruding forwards from a front ends of the two side portions 12. The front ends of the two guiding portions 13 are formed with a guiding slope 131 respectively, thereby guiding the insertion into the corresponding connector. Further, each guiding portion 13 is provided with a trough 132 at one side adjacent to the base portion 11 (refer to
The terminals 20 are made of metallic materials having electric conductivity. Each terminal 20 has a contacting portion 21 and a soldering portion 22 formed by extending from the contacting portion 21 (also refer to
The pair of locking pieces 30 are made by means of pressing metallic materials. Each locking piece 30 comprises a base portion 31, a hook 32 and a pressing portion 33. The hook 32 is formed by extending from one end of the base portion 31. The pressing portion 33 is formed by extending and bending the other end of the base portion 31.
The base portion 31 is provided with a pivot hole 34 for being fitted with the pivot shaft 16 of the insulating body 10. The locking piece 30 is formed with an elastic arm 35 by means of extending from a wall surface of the pivot hole 34. The elastic arm 35 is formed into an arc and extends into the pivot hole 34. The distal end of the elastic arm 35 is a free end and corresponds to the abutting surface 163 of the pivot shaft 16.
The metallic casing 40 is made by means of pressing. The metallic casing 40 is formed with two first connecting portions 41, two second connecting portions 42 and two third connecting portions 43 by bending downwardly at proper locations (
In assembling the connector of the present invention, the terminals 20 are inserted forwards into the terminal troughs 14 from the rear of the base portion 11 of the insulating body 10.
The two locking pieces 30 are accommodated in the two accommodating troughs 15 respectively, and the hook 32 of the locking piece 30 extends outside the guiding portion 13 via the trough 132. The pressing portion 33 extends outside the side portion 12 of the insulating body 10.
The pivot holes 34 of the two locking pieces 30 are fitted with the two pivot shafts 16 of the insulating body 10 respectively, so that the two locking pieces 30 can use the two pivot shafts 16 as spindles to rotate with respect to the insulating body 10. One side of the elastic arm 35 of the locking piece 30 abuts against the curved surface 162 of the pivot shaft 16 (also refer to
The two first connecting portions 41 and two second connecting portions 42 of the metallic casing 40 are fixed into the first fixing holes 121 and the second fixing holes 122 of the two side portions 12 respectively. The two third connecting portions 43 are fixed into the third fixing holes 133 of the two guiding portions 13 respectively. The locking holes 44 of the metallic casing 40 are locked with the locking bodies 17 of the side portion, so that the metallic casing 40 can be mounted on the insulating body 10.
When the connector is connected with a corresponding connector, the hooks 32 of the locking pieces 30 can be buckled to locking holes (not shown) preset in the corresponding connector, so that the connector can be connected with the corresponding connector firmly, thereby preventing loosening or falling off.
When the connector is to be detached from the corresponding connector, the user can press the pressing portion 33 of the locking piece 30. With the rotation of the two locking pieces 30 with respect to the insulating body 10 and the elastic deformation of the elastic arms 35 abutting against the pivot shafts 16, the two hooks 32 can be detached from the locking holes of the corresponding connector. In this way, the connector can be detached from the corresponding connector.
According to the above, in the connector with a locking mechanism of the present invention, the pivot hole 34 of the locking piece 30 is formed with an elastic arm 35. With the elastic arm 35 being fitted with the pivot shaft 16 of the insulating body 10, the locking piece 30 has a locking effect. The locking piece 30 of the present invention is simple in structure, so that it is not necessary to perform a complicated process to manufacture the locking pieces. Therefore, it is easy to manufacture and assemble the present invention, thereby reducing the whole production cost.
